Our Response to Climate Change: HK2100
Our Planet, Climate Change and Systems Thinking
1: Revisiting Progress - At What Cost?
Introduction to Modern Progress:
- Equating progress with industrial growth, tech advancements, and urban expansion.
- Environmental costs often overlooked.
- Key question: “What environmental losses have we accepted for progress?”
Example 1: Deforestation in the Amazon:
- Accelerated deforestation post-2010s for agriculture.
- Impact: Loss of biodiversity, carbon storage, and indigenous habitats.
- Trade-off: Global food supply vs. ecological preservation.
Example 2: Urbanization of Green Spaces:
- Cities like Jakarta and Beijing expanding into green areas.
- Impact: Loss of natural spaces vital for air quality and biodiversity.
- Trade-off: Economic growth and housing vs. green space conservation.
- Shale gas boom, especially in the U.S., post-2010s.
- Impact: Groundwater contamination, seismic activity, methane emissions.
- Trade-off: Energy independence vs. environmental health.
2: Beyond CO2 - The Potent Greenhouse Gas Threat
The Methane Concern:
- Methane’s Potency: Methane (CH4) is over 25 times more potent than CO2 in trapping heat in the atmosphere over a 100-year period.
- Permafrost Thaw: Recent observations reveal accelerating permafrost thaw in the Arctic, unlocking vast methane reserves.
- Impact: Methane release from permafrost could significantly amplify global warming, contributing to a feedback loop.
Other Potent Gases:
- Nitrous Oxide (N2O): Emissions from agricultural activities, particularly fertilizer use, have been rising, with N2O being about 300 times more potent than CO2.
- Industrial Gases: Hydrofluorocarbons (HFCs), used in air conditioning and refrigeration, have thousands of times the global warming potential of CO2.
2.1: Beyond CO2 - The Potent Greenhouse Gas Threat (Cont’d)
IPCC Models and Tipping Points:
- Inclusion in Models: The IPCC has recently integrated permafrost melt and methane release into their climate models, highlighting the urgency of the issue.
- Tipping Point Concerns: There’s growing scientific consensus that we might be nearing or have crossed climate “tipping points,” leading to irreversible changes.
Examples and Analogies:
- Siberian Craters: The discovery of massive craters in Siberia, believed to be caused by methane explosions from thawing permafrost, serves as a vivid illustration of the methane threat.
- The Ice-Albedo Feedback: As Arctic ice melts, it reveals darker water that absorbs more heat, further accelerating ice melt and methane release from permafrost - a dangerous feedback loop.
Reflection:
- The rising threat of potent greenhouse gases challenges us to look beyond CO2 in our climate change mitigation strategies.
- Understanding and addressing these less-discussed but highly impactful gases is crucial in our broader fight against global warming.
3: Geoengineering - A Symptomatic Treatment?
The Shift to Geoengineering:
- Large-scale interventions in Earth’s systems
- Focus shifts from emission causes to climate symptoms management
Key Approaches:
- Carbon Capture and Storage (CCS):
- Removes CO2 from the atmosphere
- Stores it underground
- Solar Radiation Management (SRM):
- Reflects sunlight away
- Aims to reduce global warming
Ethical and Practical Concerns:
- Unintended Consequences:
- Risk of unforeseen side effects
- Potential to worsen climate issues
- Moral Hazard:
- Might reduce urgency for emission cuts
- Reliance on technological fixes
4: Questioning “Progress” and “Modernity”
The Untouchable Paradigms:
- Associated with tech advancement
- Often overlook environmental cost
Need for Paradigm Shift:
- Sustainable Progress:
- Incorporates sustainability
- Balances ecological concerns
- Inclusive Modernity:
- Embraces diverse views
- Values indigenous knowledge
Example: Transition to Renewable Energy:
- Shift from fossil fuels to renewables
- Symbolizes sustainable progress
5: Academia’s Pioneering Role
Fostering Diversity and Experimentation:
- Universities as idea incubators
- Promote cross-disciplinary research
Critical Thinking and Innovation:
- Challenges established norms
- Proposes innovative solutions
5.1: Silent Spring, or Power of Narrative
Rachel Carson, Chemist | Writer | Activist
5.2 Understanding System Thinking in Environmental Context
What is Systems Thinking?
- Holistic Perspective: Complex systems as interconnected wholes
- Feedback Loops: Recognizing how different elements within a system influence one another, non-linear
Interconnectivity in Nature
- Interaction of ecosystem
- Climate phenomena as result of interactions wtihin and between atmosphere, hydrosphere, geosphere and biosphere
Understanding System Thinking
- Empowers you to see the bigger picture and recognize the ripple effects of actions
- Encourages innovative and holistic solutions to environmental challenges through interconnectedness

5.3.1 ReIntroduction of the Wolves
5.4 Interconnectedness of species
6: Urgent Climate Issues We Cannot Ignore
Rising Sea Levels:
- Coastal erosion and flooding
- Threatens communities and infrastructure
Biodiversity Loss:
- Ecosystem collapse and species extinction
- Undermines Earth’s life support systems
Water Scarcity:
- Exacerbated by climate change
- Threatens food security and stability
7: Rethinking Cooperation for a Sustainable Future
Beyond Competition:
- Emphasizes global solidarity
- Views Earth’s resources as shared
Innovative Governance:
- Develops flexible, inclusive agreements
- Empowers local action with global support
8: The Permafrost Time Bomb
Understanding Permafrost:
- Frozen ground in polar regions: 24% of Northern Hemisphere land surface
- Contains massive carbon reserves: 1700 Gigatons of carbon, 2x atmospheric carbon
The Thawing Threat:
- Warming temperatures causing thaw, twice as fast as global average
- Releases stored methane (25x) and CO2
- Permafrost to decrease by 30-70% by end of 21st century.
Implications for Climate:
- Accelerates global warming
- Could trigger runaway climate effects
